Simpliest network access by active directory group with native MS client?

[gek]

Hello!
Please advice me.

I need to make a connection from multiple users to private network according by Active Directory group membership over the existing smb network.

I see a couple of solutions but they aren't suitable:

1. OpenVPN with AD auth. -> fine but there is no native client in windows.
2. IPSEC+L2TP+mobile clients -> i have tried that several times in previous pfsense versions but no success.
3. ISAKMP + mobile clients + AD authentication -- is it possible? is it a working solution ?

May be there is any other solutions?

You should be able to use mobile IKEv2 with EAP-Radius as shown here:

@stephenw10 Thank you for advice.
But there is may only be a maximum of 50 RADIUS clients as Windows Server Standard Edition.
Is there way to escape radius authentication and use only active directory authentication instead ?

[stephenw10]

Not using IKEv2. LDAP doesn't support the hashed passwords sent by the EAP types we have. I guess you would need EAP-GTC but that is considered weak.
For standard xauth types you have to use IKEv1.

Or change the Windows server version.

I haven't tested it myself but winradius might help with that 50 user limit

You would probably still be afoul of the M$ CALs somewhere.

I say that's a constant regardless of what you do :)
